GEORGE RYAN, OF BRANTFORD, ONTARIO, CANADA.

FEED-REGULATOR FOR MACHINES FOR SPINNING HEMP, 84.0.

SPECIFICATION forming part of Letters Patent No. 398,848, dated March 5,1889.

Application filed July 7, 1888. Serial No. 279,295. (No model.)

To a whom it 771/01] (YO/ACCT"!!! Be it known that I,GEORGERYAN,111aCl1ll1- ist, of the city of Brantford, in the county ofBrant, in the Province of Ontario, Canada, have invented a certain newand Improved Feed-Regulator for Machines for Spinning Hemp, &c., ofwhich the following is a specifioa-tion.

The invention relates to a new and useful feed-regulator for machinesfor spinning manila and sisal hemps and other fibers, especially forbinding-twine and ropeyarns.

The object of the invention is to arrange a simple device by which thesliver feedrollers shall be instantly and automatically stopped themoment that any over thickness in the sliver reaches the nipper, and itconsists in the peculiar combinations and the construction andz'lrrangoment of parts, all as more fully hereinafter described andclaimed.

'l igure l is a perspective view showing the portion of the spinnerconnected with my invention. Fig. 2 is an enlarged detail of the nipper,partlyin section. Fig. 3 is an enlarged view, also partially in section,of the drivinggear for fced-rollers A is the drivingpulley, which isconstantly in motion while the i'nachine is in operation. This pulley isconnected by a belt, B, to the pulley C, secured to the spindle D.

E is a pulley loosely journaled on the spindle D. This pulley E has apawl, F, pivoted on it, as indicated, and designed to engage with aratchet-wheel, G, which is rigidly fastened to the pulley C or spindleD.

II isa lever pivoted on the pulley E, through which a hole is made topermit the passage of one end of the lever H, so that it may projectbelow the pawl F, as indicated in Fig. The other end of this lever IIextends toward an inwardly-beveled flange, a, formed on the.

pivoted at b, as shown, and one end of it is said nipper, and a spring,T, for holding the forked to engage with the wheel I. Its other end hasa pin, (1, projecting from it and fitting into an elongated hole made inthe end of the leverK. This lever is pivoted at e, as shown,

and its other end connects with the base of the nipper L. This nipper issupported on the upper end of the bar ll, the lower end of which isconnected to a journalci'l rod, N, so that the bar M,carrying the nipperL, may rock laterally. Stops 0, adj usl ably conn ccted to the spindle Pby set-screw o, regulate the rockin distance of the bar M.

Q is a bcltconnectingthe pulley E with the pulley R, which is fastenedto the spindle oi the sliver Feed-roller S.

The tension of the nipper l. is regulated in the usual manner to permitthe proper-sized sliver to pass through it. When a thick portion of thesliver reaches the nipper, it will not pass freely through the nipper.(onsequen'tly the nipper, which is held in position by the spring T, ofsuitable tension, will be caused to instantly rock on its pivot, and, being connected by the levers Ii and J to the wheel I, the said wheel ismoved toward the pulley E, causing the beveled flange a 011 the clutch Ito come in contact with and press down the lever H, forcing the oppositeend of the said lever H upwardly and raising the pawl F out of contactwith the ratchet-wheel G, as indicated in Fig. 3. Consequently thepulley E is instantly disconnected from the spindle D, whichdisconnection of course stops the motion of the pulley E, an d throughitthe sliver feed-roller S.

\Vhat I claim as my invention is 1. A nipper, L, a pivoted bar, M,carrying said nipper, and a spring, T, for holding the same in position,in combination with the pivoted lever K, having one end connected to thenipper, a bell-crank, J, connected to the opposite end of the leverK,the revolving shaft D, the inwardly-beveled flanged wheel I,1n0vablymounted on said shaft and connected with the bell-crank, a pulley, E, alever, H, and a pawl, F, carried by said pulley E, and a ratchet-wheelcarried by said shaft D, and apulley, as C, also mounted on said shaft,for receiving the motive power, substantially as described.

2. A nipper, L, a pivoted bar, )I, carrying same in position, and theadjustable stops 0, in combination with the pivoted lever K, having oneend connected directly to the 111' pper,

- mounted on said shaft and connected with the a bellcrank, J, connectedto the opposite end mounted on said shaft, for receiving the 1110- ofthe lever K, the revolving shaft D, the intive power, substantially asdescribed. \vardly beveled flanged Wheel I, movably Brantford, June 12,1888.
